title: Protective effect of coleonol on biochemical changes produced in coronary ligation induced ischemia.
abstract: Coleonol, a diterpine prevented biochemical changes induced by coronary artery ligation in rabbits at a dose of 10 mg/kg, iv. It increased the heart mitochondrial oxygen uptake and O ratio, which may be responsible for the stabilization of heart membrane. The decrease in serum creatine phosphokinase, glutamate oxaloacetate transaminase, glutamate pyruvate transaminase phospholipase and lipid peroxide and increase in cytochrome P450, glycogen and superoxide dismutase activity by coleonol treatment could have contributed to restore myocardial integrity and cardiac function disturbed by coronary artery ligation. The cardioprotective activity of coleonol was found to be comparable to propranolol.
